Good weather into the "end" cold air li winter "arrival" Jiangsu Suqian next 5 days weather forecast

Last week the temperature changes were steady, with a week of sunny weather, which continued at the beginning of November. On November 1, Suqian City is still dominated by sunny weather, and compared with the end of October, the sun has become looming, and the whole city is still a feeling of autumn high.

After all, it is late autumn, how can the cold air not come to disturb it? The reporter learned from the meteorological department of Suqian City that this week began to be affected by cold air, and the temperature in our city has dropped, but fortunately, the weather has not changed much in the early part of this week, and it is still dominated by cloudy weather. The daytime weather is mainly cloudy from Monday to Thursday, the rainy weather is online from Thursday night, and the rainy weather is mainly from Thursday night to Sunday. The cold air on Sunday is active, affected by strong cold air, there is precipitation and a cold wave of about 7 winds, the temperature will drop by 9 ° C to 11 ° C, and the minimum temperature next Monday morning is around 2 ° C, and there is frost.

At present, it is the most beautiful golden autumn season, the leaves are beginning to change color quietly, the osmanthus flowers are fragrant, just as Suqian is in the most beautiful autumn, most of the north has entered winter.

November 7 will usher in the Winter Festival, the 19th of the twenty-four solar terms and the first of winter. In ancient times, China's folk customs took the winter festival as the beginning of winter, and at this time the cold air was significantly strengthened, which brought us no longer the autumn wind to cool, but the real sense of the wind cooling.

"Li Dong" is not the same as entering winter, so when will Suqian enter winter? According to experts from the meteorological department of Suqian City, the winter time of Suqian is generally from late November to early December. According to meteorological experts, lidong is only a solar term, and there is still a big difference between winter and meteorology. Whether winter will come early depends on the intensity and frequency of cold air in the later stage, generally for 5 days the average temperature is less than 10 ° C, that is, winter.

Recently, the temperature has been cool in the morning and evening, and the "onion-style dressing method" is still the best choice. Autumn is the time when the temperature changes most drastically throughout the year, and many citizens have cold symptoms such as "nasal congestion and runny nose and sore throat". To prevent autumn colds, we must pay attention to the cleanliness and hygiene of the living room, do not give the bacteria and viruses the opportunity to multiply, but also maintain ventilation once a day in the morning, middle and evening, for a quarter of an hour each time. It is important to note that when you sleep, close the window and do not let the wind blow on your head. When the weather is dry, you can eat more foods that nourish the yin and moisturize the lungs, such as white fungus, lilies, lotuses, etc., and can also moderately "stick to the autumn fat"; at the same time, pay attention to exercise, walking and jogging and other sports are conducive to improving body immunity.

In agricultural matters, it is recommended to seize the good weather to harvest and dry mature crops in time; the fields that have been planted should be grasped early, diseases and insects should be prevented early, and spring grass and autumn treatment should be adhered to, and chemical weeding should be carried out in a timely manner.

The winter of 2021 will form the La Niña Event

Will it be cold this winter?

According to the latest news from the National Climate Center, since July 2021, the equatorial Middle East Pacific SST has continued to decline, forming a weak to moderate intensity La Niña event in the winter. Given that there was a La Niña event in the fall and winter of 2020-2021, 2021 will be the "Year of The Double La Niña".

What is La Niña?

Since October, several cold airs have given the impression of "overnight winter". The climate forecast for this winter revealed by the executive meeting of the State Council not long ago, in which "the temperature in the north and other areas this winter is lower than that of the same period of the year, and extreme weather may occur" has attracted widespread attention.

What is "La Niña"? La Niña means "LaNia" in Spanish – "little girl, holy girl". The La Niña event refers to the phenomenon of cold water with a wide range of cold water in the middle and east Pacific Oceans that is abnormal in the temperature of the sea surface in the middle and east of the equator, and the intensity and duration reach certain conditions.

Will this year be the "Year of Double La Niña"?

According to the National Climate Center, it is worth noting that following the end of the last La Niña event (August 2020 to March 2021), this winter will form the La Niña event again, that is, the "twin-peaked La Niña" occurs in the winter for two consecutive years, so the impact of La Niña on the tropics and subtropics may be more significant.

From the existing observations, the National Climate Center has always existed in the alternating temperature of cold and warm. Normally, SST should return to a neutral or warm state after the end of la Niña, so the "bimodal La Niña" phenomenon is rare.

What is La Niña's impact on our climate?

In the winter when most of the La Niña events reach their peak, the cold air activities affecting China are more frequent than usual, and the intensity is stronger, and the temperature in most parts of central and eastern China is lower than that of the same period of the year; while the tropical and subtropical areas will cause the water vapor conditions in the southern part of China to deviate significantly from the same period of the year due to the impact of the La Niña event, which is not conducive to the formation of precipitation.

According to the comprehensive analysis of the five La Niña events that occurred from 2000 to 2018, in terms of temperature, in the winter of the La Niña year, the temperature in most parts of central and eastern China was generally lower than that of the same period of the year, of which the northeast and eastern Inner Mongolia were the most significant, with the temperature being 1 °C to 2 °C lower and the local temperature being more than 2 °C. However, it is worth noting that in the winter of 2007-2008, the temperature in most parts of Heilongjiang, northwestern Jilin and eastern Inner Mongolia was 1°C to 2°C higher.

Will the temperature in our country be low this winter?

Many people still remember the snow disaster in southern China in 2008. Indeed, that year the Northern Hemisphere was also affected by the La Niña incident. Affected by the La Niña incident in 2007-2008, from January 10 to February 2, 2008, China was hit by four low-temperature rain, snow and freezing weather processes. Low-temperature rain, snow and ice disasters have a wide range of impacts, involving nearly 2/3 of the country's provinces (autonomous regions and cities), including 20 provinces (autonomous regions and cities) such as Guizhou, Hunan and Hubei.

However, experts from the National Climate Center said that the appearance of blizzards in many parts of the south can be said to be a small probability of extreme catastrophic events, and the snow disaster in 2008 is more complicated, in addition to the low temperature caused by the cold air caused by La Niña and the cooperation of water vapor in the south, it does not mean that there will be a large-scale snow disaster every time the La Niña event occurs. Moreover, the La Niña phenomenon is divided into "weak, medium and strong", and the impact of different levels of La Niña phenomenon on the winter temperature in China is also different.

Will this year be a "cold winter"?

Through the analysis of 15 La Niña events in history since 1951, it is found that there are 10 La Niña years in China's winter temperature is low, and 5 La Niña years in China's winter temperature is high. That is to say, not every La Niña year's winter average temperature is low; after the La Niña event, the probability of winter coldness in China is indeed greater, about twice the probability of warmness.

In addition, the National Climate Center reminds that it should be noted that cold temperature does not equal cold winter. "Cold" and "warm" are only compared to the average situation, while "cold winter" and "warm winter" are different and have strict standards.
